“…Although ingested soil may be a source of mineral nutrients for animals (Thornton and Abrahams, 1983), several studies pointed out soil as being one of the main matrices for pollutants transfer to outside-reared animals (Beresford and Howard, 1991;Fries, 1995;Matscheko et al, 2002). Lipophilic properties of the persistent organic pollutants are responsible for their adsorption on soil components, which enables soil to retain and accumulate pollutants in the horizon surface longer than the other matrices (also called memory effect) (Jones et al, 1989;Duarte-Davidson and Jones, 1996). Therefore, the exposure of free range animals to pollutants is closely linked to the amount of soil ingested which can be particularly high for some ruminants, up to 14% of the daily dry matter intake (DMI) in cattle (Fries et al, 1982), and up to 30% of DMI in sheep (Thornton and Abrahams, 1983) reported on pastures in very extensive temperate systems.…”

Soil is the main matrix which contributes to the transfer of environmental pollutants to animals and consequently into the food chain. In the French West Indies, chlordecone, a very persistent organochlorine pesticide, has been widely used on banana growing areas and this process has resulted in a long-term pollution of the corresponding soils. Domestic outside-reared herbivores are exposed to involuntary soil intake, and tethered grazing commonly used in West Indian systems can potentially favour their exposure to chlordecone. Thus, it appears necessary to quantify to what extent grazing conditions will influence soil intake. This experiment consisted of a cross-over design with two daily herbage allowance (DHA) grazed alternatively. Six young Creole bulls were distributed into two groups (G1 and G2) according to their BW. The animals were individually tethered and grazed on a restrictive (RES) or non-restrictive (NRES) levels of DHA during two successive 10-days periods. Each bull progressed on a new circular area every day. The two contrasting levels of DHA (P < 0.001) were obtained via a different daily grazing surface area (RES: 20 m 2 /animal, NRES: 31 m 2 /animal; P < 0.01) offered to the animals by the modulation of the length of the tethering chain (RES: 1.9 m, NRES: 2.6 m). These differences in offered grazing areas resulted in DHA of 71 and 128 g DM/kg BW 0.75 , respectively for RES and NRES treatments. As expected, the animals grazing on the reduced area realized a lower daily dry matter intake (DMI) (RES: 1.12 kg/100 kg BW, NRES: 1.83 kg/100 kg BW; P < 0.05) and present a lower organic matter digestibility (RES: 0.67, NRES: 0.73; P < 0.01) than NRES ones, due in part to the shorter post-grazing sward surface height (RES: 3.3 cm, NRES: 5.2 cm; P < 0.01) of their grazing circles. Soil intake was estimated on an individual level based on the ratio of the marker titanium in soil, herbage and faeces. Grazing closer to the ground, animals on RES treatment ingested a significantly higher proportion of soil in their total DMI (RES: 9.3%, NRES: 4.4%; P < 0.01). The amount of ingested soil in the diet was not significantly different between the two treatments (RES: 98 g/100 kg BW, NRES: 78 g/100 kg BW; P > 0.05) due to the lower DMI of RES compared with NRES treatment.

“…The most frequently mentioned uptake pathways of PAHs in plants are: (1) their root uptake from soil solution, and subsequent translocation from roots to shoots in the transpiration stream; (2) absorption by roots or shoots of volatilized organics from the surrounding air by shoots; (3) uptake from contaminated soil and dust followed by retention in the cuticle or penetration through uptake and transport in oil channels which are found in some oil-containing plants such as carrots [7,8]. Gao and Zhu (2004) studied the root uptake of PAHs by various plant species, and found that plant accumulation of PAHs correlated with oil PAHs concentration and plant composition [9].…”

In a field experiment, the transfer of polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) from contaminated soil to maize (Zea mays L.), sunflower (Helianthus annuus), poplar (Populus nigra × P. maximowiczii) and willow (Salix × smithiana) and the distribution of PCB congeners in maize and sunflower was investigated. The former waste incinerator in Hradec Králové (Czech Republic) was chosen for the experiment. Results of plot screening showed heterogenous contamination by PCBs and PAHs. PCB soil contamination was evidently caused by Delor 106 or Aroclor 1260 stocking and PAH contamination by chemicals containing fluoranthene, benzo/b/fluoranthene, phenanthrene and pyrene. Tested plants were planted on a contaminated field site, in soil contaminated with 1530 µg/kg of total PCBs and 0.138 and 3.42 mg/kg of total PAHs. The results show that maize and sunflower roots accumulated the most PCBs from soil. These plants accumulated hexa- and heptachlorobiphenyl congeners more than tri-, tetra-, and pentachlorobiphenyl congeners. Total concentrations of PAHs in tested plants ranged from 0.096 to 1.34 mg/kg. The highest phenanthrene concentration was found in aboveground biomass of sunflower and the highest concentration of pyrene, in maize roots.

“…One of the entry pathways to the environment for these azole biocides is via the application of sewage sludge as fertilizer (biosolid) in agriculture, which has been considered as a sustainable practice in many countries such as Australia, United Kingdom and United States (Duarte-Davidson and Jones, 1996;Langdon et al, 2012;USEPA, 2012). In China, the application of biosolids on agricultural land is still not allowed due to concerns with various contaminants in the biosolid (Daughton and Ternes, 1999;Gottschall et al, 2012;Kinney et al, 2008;Langdon et al, 2012;McClellan and Halden, 2010;Walters et al, 2010).…”
